Secondary Members in the PEB industry refer mostly to longitudinal roof and wall members that are roll formed from galvanized coils. Secondary members used in a PEB include steel purlins, side runners, fascia Channels, door posts, window posts, rafter stays, and column stays base angles and other miscellaneous structural parts.

• ”Z” sections acting as longitudinal roof purlins and longitudinal wall girts that connect to columns & rafters and support exterior roof and wall panels.
• "C” sections used primarily in framed openings and as a transition member between partial block walls and wall panels.
• Steel Deck used to support concrete slabs in second level flooring.
• Secondary structural framing shall refer to purlins girts, eaves struct, wind bracing, flange bracing, base angles clips and other miscellaneous structural parts.
• Secondary structural framing shall refer to purlins girts, eaves struct, wind bracing, flange bracing, base angles clips and other miscellaneous structural parts.
• Eaves struts are formed "C"- sections, 200-300 mm. deep with a 64-100 mm. wide top flange, a 100 mm. wide bottom flange, and both are formed parallel to the roof slope. Each flange has a 20 mm. stiffener.
• Rod bracing shall have a minimum yield strength of 250 mn/m2 (36000 psi) and will conform to the physical specifications of ASTM A-36 or equivalent. All other miscellaneous secondary members shall have a minimum yield strength of 250 mn/m (36000psi).

PEBs offer you choice of 5 different types of roofing and cladding systems that enhance the aesthetic appeal of the building and are ideally suited for rapid and low cost construction.

• Typical roof, wall and linear panels shall be color coated 26 gauges, galvanize steel ,ribbed panels ,(other materials and thickness available upon request)
• Base material for color coated galvanized steel panels shall have minimum yield strength of 345 mn/m (50,000 psi) and will conform to the physical specification of ASTM A-446 or equivalent.
• The zinc coating is a hot dip galvanization process conforming to ASTM specification A-525 with a coating class of G90 (0.90 0z/ft or 275 g/m) or its equivalent.
• The painting shall be baked enamel polyester (color blue or gold) with a firm thickness of 1.0 MIL the reverse side shall be white the 0.50 MIL thickness.

• "SHMICO RIB" panel shall have 40 mm. deep major ribs which taper in width from 35 mm to 65 mm, and are spaced 350 mm. on center. Between major ribs is additional minor stiffening ribs spaced at 117 mm. on center. Each panel shall provide one meter coverage.
• "SHMICO WALL " panel shall have 40 mm deep major ribs which taper in width from 35 mm to 65 mm, and are spaced 350 mm.on center between major ribs are additional minor stiffening ribs spaced at 117 mm on center .Each panel shall provide one meter coverage.
• "SHMICO DECK” panel shall have 40 mm deep major ribs which taper in width from 35 mm to 65 mm, and are spaced 350 mm. on center .Between major ribs are additional minor stiffening ribs spaced at 117 mm. on center. Each panel shall provide one meter coverage.

• Unless specified otherwise, all wall and roof panels, flashing, trim and other exposed galvanized steel surfaces shall be color coated.
• Color of panels and corner trim shall be selected by the customer from AlShahin' s standard colors.
• The gutter, downspouts, rake trim, eave trim and door flashing shall be white unless otherwise selected from AlShahin' s standard colors.
